Optimized Acetylene/Carbon Dioxide Sorption in a Dynamic Porous Crystal
Abstract
The low compression limit of acetylene (C(2)H(2)) and its similarity to carbon dioxide (CO(2)) challenge the development of novel adsorbents. We illustrate in this report that the unique static and dynamic pore characteristics of a metal azolate framework, [Cu(etz)](n) (MAF-2, Hetz = 3,5-diethyl-1,2,4-triazole), can combine to show extraordinary C(2)H(2)/CO(2) sorption behaviors, which have been elucidated by a combination of gas sorption measurements and single-crystal structure analyses of the sorption complexes of both C(2)H(2) and CO(2). As demonstrated by single-crystal X-ray crystallography, C(2)H(2)/CO(2) hexamers are confined inside the nanocages of MAF-2 in different configurations. The subtle difference between C(2)H(2) and CO(2) is magnified by consequent framework dynamics, which produce sigmoid isotherms that are optimized for practical adsorptive applications. Large C(2)H(2) uptake (70 cm(3) g(-1)) and high C(2)H(2)/CO(2) uptake ratio (3.7) at 298 K, 1 atm as well as facile gas desorption are revealed. Since the C(2)H(2) uptake at 298 K, 1 atm is far from saturation (119 cm(3) g(-1)), MAF-2 permits a usable C(2)H(2) storage capacity 20 times higher than its volume or 40 times higher than that of a gas cylinder working between practical limits of 1.0-1.5 atm.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
